Kanzakiflavone-2 (I), a new flavone has been isolated from the ethereal extract and three known compounds, iridin (VI), mangiferin (VII) and isomangiferin (VIII) were isolated from the n-butanolic extract of Iris unguicularis POIR. respectively. The structure of kanzakiflavone-2 (I) has been determined as 5, 4'-dihydroxy-6, 7-methylenedioxyflavone by chemical and spectral means.
